machine piles the goods together in cylindrical, cone shaped orsimilarly formed hollow bodies; hereinafter referred to a's bundies orgrain cylinders, and ejects them in this form, whichthey retainby'reasonof twisting and compressing action imparted thereto. The bu ndles soformed are more readily dried than ordinary sheaves-,which is a greatadvantage when the harvesting takesplace in wet weather. 7

In the drawings a constructional embodirnent is shown, by way ofexample, of one forrnserving as a right-hand, cutting machine accordingto the invent on.

The cylinder 2 is concentric with and-con nected to thebuter runningwheel 1. "On the inside of the outer running wheel 1S a toothed rim 3fitted withsmall grooves 3'.

lntheseisrnall grooves 3 at for example three points, adjustable arms 5of the frame 6 of themachine engage by the medium of the rollers 4; inthis frame is secured the shaft or beam 7 The outer runningwheel 1 canrotate about the rollers at of the frame 6, and on drawing themachinealong by pulling the shaft rolls on the ground. The axle 8 of theinner cylin der 9 is arranged concentric'with cylinder 2 and rotatablein frame 6. Between the outer cylinder 2 and the inner cylinder 9 is ahollowspace 10 across the entire width of the running wheel, in whichthe grasses and cereals are brought, fastened together and formed into acylindrical bundle. At the side, the frame 6 is provided with a support1.1, which is carried at its support 11, arearranged transporting webs,

for example 14, 15, of cloth orthe like, these havingthe object oftaking the reaped crop and conveying it to the annular cylindricalhollow space between the parts 2 and 9, which can be accomplished invarirus ways. The Webs may be said to'constittte a platform on to whichthe crops fall as they are cut by the device 12.

no form is shown in front view. plan and side View in Figs. 1, 2, and 3respectively. The reanedcrop is conveyedfrom the cutting device 12 byaspecial endless web 15 to the main endless web 1 1 provided with studsto aid the transportation and. working transversely to the drivingdirection of the machine. I

I Since the cut straws are moved with their ears foremost, by the web15in opposition to the driving direction of the machine; and by theendless web 14 transverse to the driving direction, a turning of thecorn and a forwarding of the ears towards the hollow cylinder iseffected. On the side away from the cutting device, the web l l isbounded by a further endless upright web 16, which it self moves asquick or quicker than the web l t. The tray-like slide 17, whose shapechanges gradually from the flat ofthe surface of the horizontaltransporting web 14 to the curvature'of the hol ow, cylinder, guidesthe'cut products from the platform tothe hollow cylinder. In thecylindrical hollow space 10 move the longitudinally mov able rams 18(Figs; 1 and. 4-.) connected together more or less in dovetailedmanner." These are guided by'means of the suitably formed arms 19, on acurved rail 20 fixed to the frame 6in such a way that at the deliverypoint of the tray-shaped slide 17 they are entirely withdrawn from theannular space, yet they are completely pushed into the said cylindricalspace at the diametrically opposite point. Upon rotation of the workingcylinder therams 18 are carried along therewith either by naturalrubbing or in any convenient manner. It is therefore evident that thereapedcrops whichare con'veyedto the hollow space from the platform overthe tray 17 are gradually compressed by the rams and pushed forward. Thereaped crops in'this way strike against the cogs of the wheels 21,projecting through ill) the inner cylinder 9 into the hollow space 10,two or more of which wheels are arranged radially to the hollowcylinder. The cogs ot the wheels 21 engage with the endless screw 22,which is rotatably mounted on the axle 8, but can be coupled thereto bythe couplings 23. At the beginning of the work the two wheels 21 and theat present uncoupled screw 22, stand still relative to the self-rotatingcylinder; with increased feeding of the reaped crops and increasedpressure the wheels 21 are turned'by the grain cylinder in the directionot the arrows a, the endless screw is displaced along the axle 8 towardsthe left and coupled thereto through the coupling 23. The end less screwhereby receives the same speed of revolution as the axle 8. This is suchthat now the wheels 21 receive a rotation opposite to the direction oi?arrows (L, and with their cogs retard the forward movement oi thecylinder o t' grain in the hollow cylinder in the direction of arrows b.The rotating motion of the axle 8 is derived, as shown in Figs. 1 and 2,through the change wheels 24, 25, the spur wheels 26, 27, the wormwheels 28, 29, the pair of spur wheels 30. '1 and the pair of bevelwheels 33 "a shaft 35 which is coupled and uncoupled by means of thecoupling 34 and driven by cog wheel 36 mounted thereon from the toothedrim 3 of the track wheel 1. By varying the wheels of the changegear 24,25, a change in speed of the endless screw 22 and hence ot the cogwheels 21 is obtained, so that 1t is possible to adjust the forwardvelocity of the cylinder of grain according to the strength and qualityof the straw, audits degree of dampness in any given working conditions.

The inner cylinder 9 extends beyond the topmost ram 18 a distance ywhich is approximately equal to the desired length of the finishedbundle, referred to as the grain cylinder. The outer cylinder 2 projectsbeyond the inner cylinder 9 a further distance in which is slightlygreater than the distance 3 and is cut away to provide an ejectionaperture 53. A cylindrical sleeve 37 is rotatably mounted upon the outerend of the cylinder 2 and has an aperture 52 there n, which from time totime comes into registration with the aperture 53 to allow the graincylinders to be.discharged from the machine as they are completed. The.

sleeve 37 will rotate together with cylinder 2 by reason of the frictiontherebetween, but its rotation is adapted to be arrested by a projection42 thereon coming against arm 41 of a vertical spindle 40 journaled inthe frame 39 which is rigidly secured to frame Got the machine. The arm41 is normally held by means of a spring 45 in a position out of thepath of abutment 42 so that the sleeve 37 is free to rotate. A roller 38is carried by an arm secured to the upper end of spindle 40, andprojects somewhat within the cylinder 2 and in line with the annularspace 10. This arrangement results in that as the grain cylinder formedin space 10 is advanced into the discharge end of cylinder 2, it pressesagainst the buffer roller 38, turns the spindle 40 against the action ofspring 45, thereby moves the arm 41 into the path of abutment 42 so thatthe sleeve 37 is arrested with its aperture 52 directed downwards andrearwards, and as aperture 53 in cylinder 2 comes into re istration, agrain cylinder of length a: will fall by its own weight out on to thefield, as hereinal'ter explained. Actuation of the butter roller 38 alsointerrupts the feed of the conveyer mechanism by disengaging thecoupling 34 by means of draw-bar44 pivoted to a. crank arm 43 securedupon the lower end olt' spindle 40. i

The division of one grain cylinder from the tollowing one is effectedaccording to the preterred method in this Way. In operation the machineis first worked until a cylinder of grain is formed extending from therams 18 to the butter roller 38, pushing back the latter and thuscausing the clutclr34 to be disengaged and interrupt the advance offresh material to theannular space 10, and at the same time arrestingthe sleeve 37 as above described so that the aperture 53 comes intoregistration with the aperture 52. This long grain cylinder is then cutinto two approximately at the position indicateo by arrows .2, by handor in any other convenient manner and the portion thus severed will fallout. Now during the time that one grain cylinder is undergoing ejection,which corresponds approximately to one revolution of the cylinder 2, therams 18 act upon the rear end of the following grain cylinder tocompress same without additional material being added. So, when thebuffer roller 38 is allowed to be brought back by its spring 45 into thenormal position incidentally the sleeve 37 is released, thecoupling 34re-engaged, more material isfed forward to the rams by the conveyor, and

the formation of another grain cylinder is commenced. Thus, byinterrupting the conveyor mechanism. a division is made betweenconsecutive grain cylinders which suffices to enable said cylinders tofall out, one by one, as they reach the ends of cylinder 2 and cause theexit apertures 52, 53 to come into appropriate registering position.

The separation of the firstformed grain cylinder by cutting as describedabove might in some cases be effected alternatively by operating thebulfer roller mechanism manually when a m is first formed.

The treatment which the stalks receive grain cylinder of length withinthe annular space 2 enables the finished bundles to retain their shapewithout additional binding means as is necessary for ordinary sheaves.The bundles will lie on the ground on their sides until stood on endmanually 01' otherwise when they will dry much more readily thanordinary sheavesby reasonof their form, particularly if raised somewhaton one side so that a through passage for air is provided.

It is obvious that the machine above de scribed. admits of variousmodifications without departing from the scope or spirit of theinvention. For example the platform can also be constructed according toFigs. 6 and 7, where two endless webs work behind each other in the samedirection; the web 46 moves quicker than web 47, so that here also thestalks are turned and conveyed in the proper direction to the tray andso to the hollow cylinder.

In Figs. 8 and 9 a further embodiment of the platform is shown. Thereare two endless webs 48 and 49 disposed one over the other between whichthe reaped crops are taken and conveyed to the slide and so to thehollow cylinder. The cut goods fall first on the upper web 48 whichcarries them outwardly. At '50 an interchangeable plate 51 of dimensionsaccording to the length of the grain is disposed between the cut stalksand the smaller endless web 49. i The cared .ends of the stalks areseized while the straw ends fall on the polished sheet 51. Here also theforwarding of the cared ends as against the straw ends is effected andthe reaped crops are conveyed in appropriate position between the websto the slide and so to the hollow cylinder.

The machine can be adapted for driving through narrow and small ways inknown manner by means of displaceable wheels and for drivinglongitudinally and also so constructed that the platform can be closedup.
